Running Shorewall v5.0.14.1 on Fedora Server 4.8.15-200.fc24.x86_64 configured with two interfaces (br0 and team0). Interface br0 connects to Internet while the team0 interface connects wireless local devices (LAN) (printers, tablets, roku, etc.). The team device is configured for loadbalancing using two nics. Additionally, DHCP and DNS answer requests on team0 interface. Shorewall flags broadcasts as martians. Intermittently devices sending requests to DHCP are also flagged as martians. Sample of messages appear as follows (first is broadcast; second is device requesting IP address:

My question(s): Is there a configuration error in device team0 shorewall interface configuration causing this behavior? Is there a troubleshooting method to isolate this behavior?
Thanks in advance.
